[Wikipedia] Range, Description, Toxicity: Solanum wallacei, also known as Catalina nightshade,[2] Wallace's nightshade, Northern island nightshade, or wild tomato, is a perennial plant that produces purple flowers, but otherwise resembles a tomato plant. The foliage and purple-black berries are poisonous. This rare plant is native to canyons and hillsides on two of the three Channel Islands of California, as well as Guadalupe Island off Baja California.[3] It blooms in April and May. Wallace's nightshade is named for William Allen Wallace (1815-1893) who collected samples from the Los Angeles area around 1854. Also named for him is the woolly daisy, (Eriophyllum wallacei), among others. (link added by Mary Ann Machi)
